APC 10x8, 10X9 or 10x10 possibly?
Prop choice is not a very exact science because everyone has their own opinion of what is "good."
Unfortunately that seems to mean you have to stock up on a bunch of sizes and experiment until you find the one that is best for you and your plane.
Luckily the 10 to 13 inch props are not extremely expensive; but in total you will spend a lot to experiment.
